Our Best Bet for Colonizing Space May Be Printing Humans on Other Planets

Assuming human deep space travel turns out to be not just incredibly dangerous, but perhaps “crazy idiotic” and “laughable,” as Harvard biologist Gary Ruvkun put it, the tenacious dream of an interstellar civilization forces some out-of-the box thinking. What if, instead of rocketing humans to other planets, we made an exact copy on site?

Adam Steltzner, the lead engineer on the NASA JPL’s Curiosity rover mission, believes that to send humans to distant planets, we may need to do one of two things: look for ways to game space-time—traveling through wormholes and whatnot—or rethink the fundamental idea of “ourselves.”

I think I mooted this idea quite some time ago on this forum

I think it’s a good idea but there are some humans I’d like to send to other planets anyway.

Don’t print humans, just synthesize a single cell and grow them from that.
